AXLE-GAG E.

SPECIFICATION forming part of Letters Patent No. 460,434, datedSeptember 29, 1891.

Application tiled March 27, 1891. Serial No. 386,675. (No model.)

axle-gages; and the object of myinvention is to provide a simple andconvenient device which will accurately test an axle to indicatewhether'it is properly turned and the wheels properly set thereon, andwhich may also be used as a straight-edge and rule.

To this end my invention consists in an axle-gage constructedsubstantially as hereinafter described and claimed.

Reference is to be had to the accompanying drawings, forming a part ofthis specification, in which similar figures of reference indicatecorresponding parts in all the views.

Figure 1 is a side elevation of the gage, showing its application to anaxle. Fig. 2 is a broken enlarged plan view of the gage. Fig. 3 is anenlarged detail side elevation showing one ofthe sets in position on thebar, and Fig. 4 is a cross-section on the line 4 4 of Fig. 3.

The gage comprises the flat bar 10, the slid` ving sets 11, which moveon the bar, and the means for adjusting the sets. The bar 10 is made,preferably, of flat steel, and is provided throughout its entire lengthwith gage-marks indicating the fractional parts of inches, and the marksmaybe produced so as to measure the smallest practical fraction of aninch, if desired.

The sets 11 are provided with four flat faces 12, which are placedequidistant around the periphery of the sets, and three ot the faces ofeach set are provided with set-screws 13, 14, and 15, the fourth facebeing provided with a thu mb-screw 16,which projects through the set andimpinges on the bar 10, so that vby tightening the thumb-screw the setmay be held in a desired position on the bar. The set-screws areaccurately adjusted by means of a small wrench, so thatl the outer endsof the set-screws 14 will be level. The setscrews 13 are adjustedl sothat the screws in the middle set-screws, so that when the mid` dleset-screws are against the arms of the axle near the collar the outerset-screws will bear against the arms at the ends, the difference in thelengths of the set-screws corresponding to the taper of the arms. Thefront set-screws 15 are arranged in the same manner, the outer ends ofthe set-screws on'the middle sets being level and the outer ends of theset-screws on the outer sets being level; but the outer set-screwsproject beyond the inner ones to correspond to the taper of the arms ofthe axle.

The difference in the lengths of the outer and inner set-screws isclearly illustrated in Fig. 2.

In using the gage the inner sets 11 are adjusted so that the set-screwson the sets will fit against the collars 18 of the axle 17 and upon theinner surface of the arms 19 of the axle, and the outer sets areadjusted so that their set-screws will impinge upon the arms 19 of theaxle on the outer ends of the arms. The set-screws are adjusted in themanner described, so that the appropriate set-screws will fit the bottomand front and rear sides of the axle and bear upon the arms when theaxle is properly turned, and if there is any defect in the axle it willbe indicated by the sets. When the sets are removed from the bar 10, thebar may be used as a rule or as a straight-edge.

Having thus fully described my invention, I claim as new and desire tosecure by Letters Patent- An axle-gage comprising a bar and a series ofsets held to slide on the bar, the sets having equidistant set-screwsprojecting from three sides and a thumb-screw inthe fourth side adaptedto impinge on the bar, substantially as described.
